I would not recommend that you use a bike for commuting, it's dangerous and uncomfortable, still camaro will be many times better, but if you choose between 250cc and 300cc I would not recommend either, because they are too heavy in the management of bikes for beginners, better to take the Harley Davidson Iron 883 put on his
best true dual exhaust for harley will look cool and easy and convenient to manage, and still costs reasonable money.
